Climate Chart of Jefferson City, USA

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

The monthly mean temperature is lowest in January, at 0.4 °C, and highest in July, at 26.0 °C. These are averages for whole months, not daytime highs or a description of the temperatures visitors will experience on every day. Across the calendar-month means, the unweighted mean is 13.7 °C. It provides an overall reference point, rather than a day-weighted annual average.

Rain

Mean daily rainfall reaches its highest monthly average in May, at 4.13 mm/day; January has the lowest, at 1.54 mm/day. The contrast identifies months with different average daily amounts, but does not establish how often rain falls or guarantee dry days in the lower-rainfall month. The unweighted mean across the monthly daily-rainfall averages is 2.91 mm/day. These figures are daily means, not monthly rainfall totals.

Snow

Mean daily snowfall is highest in February, at 4.43 mm/day. The unweighted mean across monthly snowfall averages is 0.99 mm/day per day; these averages do not indicate the number of snowy days, snow depth, snow cover or skiing conditions.

Sunshine

Average daily sunshine is highest in July, at 11.65 hours/day, and lowest in December, at 5.64 hours/day. The monthly means can help frame expectations for sunshine, but sunshine duration is not the same as day length and does not promise clear skies on a given day. The unweighted mean of the monthly sunshine averages is 8.53 hours/day per day, an overall reference rather than a day-weighted annual figure.

Best Travel Time Guide for Jefferson City, USA: Ideal Seasons and Weather Insights

If lower average rainfall is a priority, January is a conditional option: its mean daily rainfall is 1.54 mm/day. This is not a guarantee of dry weather or a measure of rain frequency, so visitors may still want flexible outdoor plans. For rain preparation, note that May has the highest mean daily rainfall, at 4.13 mm/day; consider packing a rain layer or keeping indoor alternatives available rather than assuming rain on any particular day. Visitors prioritising cooler monthly averages may consider January, when the monthly mean temperature is 0.4 °C. This is not a forecast of daytime highs or a guarantee of the temperature during a visit.

For outdoor sightseeing planned around sunshine, July has the highest mean daily sunshine duration at 11.65 hours/day, while December has the lowest at 5.64 hours/day. These averages can inform expectations, but they neither specify daylight length nor ensure sunshine on individual days. Snowfall averages are also worth keeping in perspective: February records the highest mean daily snowfall at 4.43 mm/day, but that figure cannot tell visitors how many days will be snowy or whether snow will cover the ground.
